It was the second-ever success for the joint missile defense program, and a stunning technological accomplishment.
A NASA photograph revealed an extremely weird-looking iceberg. A NASA scientist explained why.
There's a telescope that can see thick rings of dust in distant star systems. And researchers want to use its data in a new way to spot hidden and migrating exoplanets.
Iridium 70 fell out of orbit Oct. 10. A few days later, one of its fuel tanks caused a stir in central California.
Are we all going to be replaced?

SpaceX will attempt to launch and land a rocket on the West Coast Sunday, and the USAF wants Californians to know in advance so they won't worry.
A new map of dark matter all over the universe could reveal things scientists don't know about dark energy.
There's something out there that physicists have never seen before, and it's coming up from the bottom of the Earth. Scientists think it's a brand-new particle.
Very close to the very beginning, scientists think, there were black holes. And now they know how to find them.

Just seven photons in a mirrored trap formed a Bose-Einstein condensate, one of the more exotic particle states — and one usually reserved for matter.
Galaxies use powerful winds to save themselves from early deaths. And researchers just spotted one from just a billion years after the Big Bang.
Jocelyn Bell Burnell shocked the physics world when she discovered radio pulsars. But the Nobel committee gave the 1974 award to her supervisor instead.
A new experiment in Italy will seek an unlikely particle that some scientists think could unlock the "dark sector" of our universe.
We live our whole lives wandering from one cloud of dust to the next. A new NASA image lets you see that for yourself.
NASA's latest images of the world from space reveal just how much of planet Earth is straight-up burning right now.
The strange radio bursts usually circle the Earth like electromagnetic ghosts, but scientists have now created and studied their shapes in a plasma chamber on Earth.
